JEEP GRAND CHEROKEE ENGINE PROBLEM

2004 Jeep Grand Cherokee • 75,000 miles

The engine is racing, being the worst when in park but also when shifting while sitting idle. What would cause that? I am concerned about cost to repair. The engine light was on but that was due to some loose hoses.

THOSE LOOSE HOSES MAY BE THE PROBLEM, IF THEY ARE A VACUUM LEAK

..........CAN YOU REPAIR THEM?........REPLACE 'EM?......HOOK 'EM BACK WHERE THEY GO?

THE CHECK ENGINE LIGHT MAY ALSO BE ON FOR........OTHER REASONS.....THERE'S ONLY "ONE LIGHT" AND WELL OVER A HUNDRED REASONS FOR IT TO BE ON......YOU MAY HAVE MULTIPLE CODES!

MANY AUTO PARTS STORES WILL SCAN FOR YOUR CODES FOR FREE

HAVE IT CODED AGAIN---THIS TIME GET THE EXACT NUMBERS---THEY WILL BE LIKE: "P0265" OR "P0171" (JUST MADE UP EXAMPLES)----POST 'EM TO US, SHOULD YOU NOT GET 'EM FIGURED OUT MORE CORRECTLY

EVEN IF THEY OFFER A DIAGNOSIS....GET THE NUMBERS......NOT WHAT THEY SAID, CODES CAN BE INTERPRETED DIFFERENTLY

SOMETIMES STUFF LIKE "LEAN ON BANK ONE" CAN BE INTERPRETED DIFFERENTLY---AS TO WHAT TO DO TO MAKE IT "NOT LEAN"

SOME FOLKS MIGHT WOULD SAY IT NEEDS AN O2 SENSOR--OTHERS MIGHT SAY YOU GOTTA VACUUM LEAK---YET ANOTHER MIGHT SAY THE INJECTOR IS MESSED UPMANY CODES ARE SIMILAR, BUT THE FIX MIGHT BE TOTALLY DIFFERENT

YOU ARE PROBABLY BETTER CYBER ORIENTED THAN I AM.......SO BELOW IS SORTA BASIC

IF IT'S NOT A VACUUM LEAK, IT COULD MAYBE BE THE IAC MESSING UPWE'LL DISCUSS IT LATER---IT'S A VERY EZ THING TO TAKE OFF AND CLEAN

KEEP US POSTED ON PROGRESS---GET US THE CODES---OTHERS WHO ARE MORE FAMILIAR WITH YOUR PLIGHT, MAY JUMP IN AND OFFER MORE INPUT
